摘 要 ：四角果科（Carlemanniaceae）科下有四角果属Carlemannia（3种）和蜘蛛花属Silvianthus（1种1亚种）。这两属建立之初均置于茜草科，此后又被多个分类及系统学家将它们移至忍冬科；1965年由Airy Shaw将它们从忍冬科独立成四角果科，得到了部分学者的赞同，但其系统位置仍存在争议，认为与与苦苣苔科、虎耳草科、马鞭草科和绣球花科等科的关系错综复杂；科下两属间的关系也仍然值得探讨。APGII认为四角果科与木樨科素馨属或女贞属近缘，但支持率不高。本文对四角果属和蜘蛛花属系统位置的研究和现状进行了评述；将Silvianthus bracteatus ssp. tonkinensis (Gagnep.) H. W. Li作为线萼蜘蛛花Silvianthus bracteatus ssp. clerodendroides (Airy Shaw) H.W.Li的异名归并；并对今后的研究提出了建议。
Abstract:Carlemanniaceae consists of 2 genera, Carlemannia and Silvianthus. There are 3 species in Carlemannia, 1 species including 1 subspecies in Silvianthus. The two genera had been put into Rubiaceae or Caprifoliaceae in the opinions of some taxonomists. Airy Shaw set up Carlemanniaceae having those two genera in 1965 and this division had been agreed by many other authors, but the systematic position of Carlemanniaceae was also in dispute even the relationship between Carlemannia and Silvianthus themselves,and the relationships with many other families, such as Gesneriaceae, Hydrangeaceae, Saxifragaceae and Verbenaceae are still very complicated and ill-defined. APGII considered its closest sister group was Jasminum or Ligustrum in Oleaceae but this conclusion was supported less. In this paper, the research references and recent materials to the family were reviewed and the scientific name Silvianthus bracteatus ssp. tonkinensis (Gagnep.) H. W. Li was treated as a synonym of Silvianthus bracteatus ssp. clerodendroides (Airy Shaw) H.W.Li. In the mean time, some suggestions have been provided for the research works in the future.
